用超导材料Nd 2CuO 4-xFx（0≤x≤0.3）测量了霍尔系数（RH）和热电功率系数（S）。对于0.1≤x≤0.3的样品，在30 ~ 175 K的温度范围内，RH均为负值。此外，随着x的增加，在100 K下由RH估计的电荷载流子密度（pH）与x成比例地增加（pH =x），直到约0.18，然后在x≥0.18时更快
Both the Hall coefficient (R H ) and the thermoelectric-power coefficient (S) have been measured using the same of superconducting Nd 2 CuO 4-x F x (0≤x≤0.3). For the samples with 0.1≤x≤0.3, the R H of every sample is found to be negative in the temperature range between 30 and 175 K. Furthermore, as x increases, the charge-carrier density (p H ) estimated from R H at 100 K increases in proportion to x (p H =x) up to around 0.18, then much more rapidly for x≥0.18
